STANGHION.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed March 8, 1907. Serial No. 361.304.

To all whom it may concern:

Be it known that I, OHARLns D. W. THRASHER, a citizen of the United States, residing at Ascutneyville, in the county of Windsor and State of Vermont, have invented certain new and useful Improvements in Stanchions; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in stanchions and more particularly to that class adapted to be used for securing stock and my object is to provide means for securely locking the parts of the stanchions together after the animal has placed its head through the same.

A further object is to provide means for preventing the animal from passing its head to one side of the stanchion when the stanchion is opened.

A further object is to provide suitable means for operating the parts of the stanchion whereby the same may be readily opened or closed.

Other objects and advantages will be hereinafter referred to and more particularly pointed out in the claims.

In the accompanying drawings which are made a part of this application, Figure 1 is a front elevation of my improved form of stanchion showing the same opened ready to receive the head of the animal. Fig. 2 is a sectional view thereof as seen on line 22 Fig.1. Fig. 3 is a sectional View as seen on line 33 Fig. 1. Fig. 4 is a front elevation of the stanchion showing the same in its closed position, and, Fig. 5 is a sectional view as seen on line 55 Fig. 4.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1 and 2 indicate sills between which are located vertically disposed posts 3, said posts being employed for forming a feeding compartment for an animal.

Located between the posts 3 is my improved form of stanchion which consists of blocks 4 and 5, said blocks being pivotally mounted upon the sills l and 2, respectively and are held in position by means of bolts 6 and 7 respectively.

Pivotally secured in slots 8 at each end of the block 4 are stanchion bars 9 and 10, said bars being held in position in the slots 8 by directing bolts 11 through the block and lower end of the stanchion bars. The upper ends of the bars 9 and 10 are adapted to engage shoulders 12 and 13, respectively, on the block 5 thereby limiting the inward movement of the bars and cause the same to rest in a vertical position when closed.

A pair of auxiliary stanchion bars 14 and 15, are pivotally secured to the block 5 by means of bolts 16, said auxiliary bars depending from the block 5 and adapted to aline with the bars 9 and 10 when said bars are closed or in a vertical position, the lower ends of the auxiliary bars being in juxtaposition to the upper surface of the block 4 when the bars are closed.

The bars 9 and 10 and auxiliary bars 14 and 15 are pivotally secured together at a point above their longitudinal center by means of bolts 17 thereby causing each set of bars to open or close in unison and in order to readily open or close said bars and lock the same in their opened or closed positions, I provide a latch 18, one end of which is pivotally secured to the bar 9 and adjacent the upper end thereof, the opposite end of said latch being pivotally secured to a lever 19 which is in turn pivotally secured to the bar 10, the free end of said lever being provided with a handle 20 so that the same may be readily grasped and rotated when desired.

When the stanchions are opened as shown in Fig. 1 of the drawings, the handle end of the lever 19 extends beyond the outer edge of the bar 10 and that end of the latch 18 secured to the lever is directed below the fulcrum of the lever and by securing a cleat 21 to the bar 9 below the latch 18, the downward movement of the latch will be limited and as the movable end thereof is below the fulcrum point of the lever 19, the stanchion bars will be held open until such time as the lever is operated to close the same. To close the stanchion bars the handle 20 is moved downwardly thereby swinging the latch 18 upwardly above the pivot point of the lever 19 and by continuous rotation of the lever, the bars forming the stanchion are drawn to a vertical position and when in this position, the latch 18 and lever 19 are parallel with each other and in the same horizontal plane, this position being best shown in Fig. 4 of the drawing.

In order to positively hold the stanchion bars in their closed position, I provide the latch 18 in its lower edge with a notch 22 so that when the stanchion bars are in their closed position, the notch 22 will take over the pivot pin 23 employed to mount the lever 19 upon the stanchion bar 10 and it will be readily understood that it will be impossible to separate the stanchion bars until such time as the notch 22 is released irom the pivot pin 23 which result is accomplished by moving the handle portion 20 of the lever downwardly.

By pivoting the bars 9 and 10 and auxiliary bars 14 and 15 together at a point above the longitudinal center of the bars, the lower ends of the auxiliary bars are extended to each side of the lower ends of the bars 9 position, I provide strips 24 which are arranged in pairs at a point adjacent the lower end of the stanchion, so that when the bars forming the stanchion are opened the lower end of the auxiliarybars will extend between the strips thereby preventing rotation of the stanchion. It will be seen, however, that as soon as the animal has placed its head between the stanchion bars and said bars are directed together that the auxiliary bars will be moved out of thepath of the strips 24 so that the stanchion may be freely rotated upon the bolts 6 and 7.

.-As the bars 9 and 10 and auxiliary bars 14 and 15 are pivoted together, it will be necessary to provide means for allowing a slight longitudinal movement of the bars and to-this end I form the bolts 6 and 7 of a greaterlength than the thickness of the blocks 4 and 5, so that when the stanchion bars are'opened, the blocks 4 and 5 may move towards each other.

It will 'now be seen that I have provided a very cheapand economical stanchion for securing animals and'one that may be readily and quickly opened or closed. It will further be seen that I have provided positive means for holding the parts of the stanchion in their opened or closed positions, and it will still further be seen that I have provided means ior preventing the animal irom passing its head to one side of the stanchion and at the same time holding the stanchion against rotation and in such position that the full opening in thestanchion will be presented to the animal.

What I claim is:

1. The herein-described stanchion comprising a pair of blocks, a pair of main bars pivotally secured to one of said blocks, auxiliary bars pivotally secured to the opposite blocks, bolts to pivotally secure said main and auxiliary bars together whereby when said bars are opened they will cross eaclrother and parallel each other when the bars are closed and means to open and close said bars.

2. In a stanchion the combination with sills; of blocks havingslots therein, means to pivotally secure said blocks to the sills, a pair of bars pivotally secured to each of said blocks, bolts to pivotally secure the bars on one block to the bars of the opposite block, a latch pivoted to one of said bars, a lever pivoted to the opposite bar and means to secure one end of said lever to one end of the latch whereby when the latch is rotated the stanchion will be opened or closed.

3. In a stanchion of the class described the combination with sills and supporting means therefor; of a pair of blocks pivoted to said sills and one above the other, a pair of upwardly extending bars pivoted to the lower block, a pair of depending auxiliary bars pivoted to the upper block, bolts to pivotally secure said bars in pairs, a latch pivoted to one of said bars, a lever pivotally:secnredtmthe opposite bar, means to secure one end 01 said lever to one end of said latch whereby when the lever is rotated the bars will be drawn to a'vertical position and paralleling each other, said latch having a slot in its lower-edge adapted to take over the pivot of said lever, whereby-the bars will be securely held when the lever iszin closedposition.

4. A stanchion of the class described, comprising a-pair of'main bars and a pair of auxiliarybars, blocks to support said main and auxiliary bars, a lever pivotally connected to the upper end of one of the main bars, and a latch pivotally connected to said lever and to the opposite main bar, said latch having'a slot'in its lower edge adapted to take over the pivot-pointofthelever-when-the bars are closed to prevent said bars from being opened until the lever is again rotated to open the bars.

In a stanchion of the class described the combination with a pair of main bars and means at the lower ends thereof to pivotally mountthe same in position; of-a pair of auxiliary bars pivotally secured to the'main bars and having supporting means at the upper ends thereof, .a latch at the upper end of one of said main bars and means carried by the opposite main bar adapted to engage said latch and open or closethe stanchion as desired.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
